[WIP] Add docker & .devcontainer

[liliankasem]

• Add dockerfile + compose to make it easy to build and run the CLI for testing
• Add .devcontainer to make it easier to setup and contribute to this project

These are initial changes, we can make more as needed.

Dotnet SDK has native docker publish integration. Can we use that instead?

https://learn.microsoft.com/en-us/dotnet/core/containers/sdk-publish

Also consider adding a launchProfile for docker, so it will be integrated with both VS and dotnet run: https://learn.microsoft.com/en-us/visualstudio/containers/container-launch-settings?view=vs-2022 -- not sure if this works off of the above docker publish, or needs a docker file separately

We can use that, but without a custom dockerfile we don't get a long standing container, and we wont have the components we need installed to create and run dotnet apps (likely the same for other stacks too).

Docker also does a much better job with caching so when you build the image and run it, it takes way less time the second time/or if no changes to the cli.

I'm down to use it in combination with a Dockerfile or something else to configure the image with everything you need to test and validate function apps and cli features, but as a stand alone I am not sold?

Will look into launchProfile.

Edit:

I think maybe the intention of these approaches/images are different. I'm trying to make it so its easy to build, run and test changes you make to the CLI, where as the dotnet container publish is good for just packaging the image itself - so different use case?

Maybe a combo of the dotnet image with .devcontainers = test environment

I'd love to move away from CoreTools and change this to Cli as well
